<p align=center><b>Release 4.2: DB-&gt;set_cache_priority</b></p>
<p>In previous releases, applications set the priority of a database's
pages in the Berkeley DB buffer cache with the DB-&gt;set_cache_priority
method.  This method is no longer available.  Applications wanting to
set database page priorities in the buffer cache should use the
<a href="../../api_c/memp_set_priority.html">DB_MPOOLFILE-&gt;set_priority</a> method instead.  The new call takes the same
arguments and behaves identically to the old call, except that a
<a href="../../api_c/mempfile_class.html">DB_MPOOLFILE</a> buffer cache file handle is used instead of the
<a href="../../api_c/db_class.html">DB</a> database handle.</p>
